The remembrance march was led by victims’ families, including the father and stepmother of 20-year-old Anthony Naiboa. Naiboa’s father said his son was targeted because he had autism.

“I just hope that someone just realizes the pain that our family, Monica’s family, as well as Benjamin’s family is going through, because justice has to prevail,” Rodriguez, Naiboa’s stepmother, said. “We own these streets! We own this community. And there has to be justice, justice has to prevail.”

On the night of the first murder, an individual can be seen on surveillance video walking through the neighborhood wearing a hoodie. Police said they are still looking for the person.

“We have no leads,” Dugan told CBS over the weekend. “We have no motive.”

However, police do see a pattern in the three victims’ deaths, all strangers but shot in the same area and in the same time frame.

On Oct. 13, Monica Hoffa’s body was found in a vacant lot. Just four days earlier, Benjamin Mitchell’s body was found less than a mile away, CBS reported.

The latest victim, Naiboa’s body was found on Thursday. He was gunned down after taking the wrong bus home from work about 1,000 yards from where Mitchell was killed.

At Sunday’s vigil, Naiboa’s father, Casimir, pointed to a part of the ground: “He was right on this floor, right here. They killed him just for nothing. Like he’s not a human, like he’s nothing.”

Patrol officers are walking the streets, in the hope of finding the killer. The department is set to hold a community meeting with residents Monday evening to discuss the murders and how to stay safe.
